HENRY A. BRAUN, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR OF TlVO- TIHRDSTO JOHN R. MCFETRIDGE, JR., AND EDVIN L. BRAUN, OF SAME PLACE.

PRESSURE DEVICE FoR BEER, etc.

SPECIFICATION forming part of Letters Patent No. 576,087, dated February2, 1897.

Application filed December 21, 1895. Serial No. 572,867. (No model.)

Be it known that I, HENRY A. BRAUN, a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invented a new and useful Improvement in Pressure Devices for Beer,Ale, and other Fluids, which improvement is fully set forth in thefollowing specification and accompanying drawings. y

My invention consists of a pressure device for beer, ale, and otheriiuids, the same embodying a tank which contains a chamber and float andis in communication with a supply of liquid and with a barrel, keg,dre., in which pressure is to be exerted, said float containing a uid inwhich the chemical or material of the chamber is adapted to dip, thusautomatically generating gas in the tank, as required, to increase thesupply in the barrel, d50., as the fluid in the latter is withdrawn,there being also an automatical cessation of the generation of the gaswhen the withdra wal of the iiuid ceases.

Figure 1 represents a partial top view and partial horizontal-section online a; cc, Fig. 2, of a portion of a pressure device embodying myinvention. Fig. 2 represents a vertical section thereof on line y y,Fig. l. Fig. 3 represents a side elevation of a portion of the device.Fig. 4. represents a side elevation of the device on a reduced scale.

Similar letters of reference indicate corresponding parts in the severalfigures.

Referring to the drawings, A designates a closed tank, within which is avessel B, the same having a circumferential hollow rim or gutter C,forming an airchamber at the top of the vessel, whereby said vessel iscaused to iioat on the water placed in said tank.

Suspended from the upper part of the tank A is a chamber D, whose bottomor lower portion is perforated and adapted to dip into iiuid in thevessel B, as will be hereinafterward described.

. The tank A is provided with a water-snpply pipe E and a gas-dischargepipe F, each pipe having a valve or regulating or controlling cock Gr.The pipe F is connected with a barrel or keg J, which contains beer,ale, and other fluid, and the pipe E is connected with a tank H,containing water for supplying the tank A.

The vessel D is adapted to contain a chemical or material, such asmarble, which, with the iiuid in the float B, such as hydrochloric acid,forms a gas of the order of carbon dioxid.

The operation is as follows z' As the gas is generated, the pipe F beingin connection with the barrel, which latter is closed, the pressure ofthe gas is exerted on the water in the tank A, thus lowering the sameand causing it to rise in the pipe E, and thereby renturn into the tankHuntil the level of the acid is below the lower level of the marble,when the generation of the gas ceases. When a quantity of beer or iiuidis withdrawn from the barrel J, the vacated space in the latter ismmediatel'y occupied by a quantity of gas leaving the tank A. Owing tothe displaced gas in said tank the pressure of the water in the pipe orcolumn E causes the water in the tank A to rise, whereby the iioat Balso rises, and the acid and marble are again in contact, when there isa further generation of gas, the pressure of which is exerted on thewater in the tank A, as before. Thus these operations continue while thefluid is being withdrawn and when the withdrawal ceases. The handles Kof the cocks Gr are so disposed that they overhang the lid L of the tankA when the cocks are opened. Consequently when said lid is to be removedfor charging thede- -vice or other purposes itis necessary to raise thelid and turn the handles upwardly, whereby the cocks G are closed andthe supply of water is cut off and the back pressure of gas from thebarrel prevented, said cocks being provided with shoulders and pins,whereby they can be opened only in the direction of the arrows, Fig. 2,it being understood that the cocks are open when the device is inoperation.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, ism

1. In a pressure device for the purpose set forth, a tank provided witha vessel', adapted to iloat in said tank, and a chamber supported insaid tank and adapted to have said float- Ioo ing vessel rise above andrecede from the bottom of said chamber, said chamber being perforated,andthe parts combined substantially as described.

2. A pressure device for the purpose set forth, consisting of a closedtank provided with Water-inlet and gas-outlet pipes, a vessel in saidtank adapted to float, and a perforated stationary chamber supported insaid tank, said stationary chamber being adapted to have said floatingvessel rise above and recede from the bottom of the same, said partspipes, and coeks in said pipes, said cocks llaving their handles locatedadjacent to the lid of said tank so as to be operated to close the cocksby the removal of the said lid, substantially as described.

5. A pressure device for the purpose stated, having a closed tank, astationary perforated chamber and a floating vessel, the latter beingprovided with an air-chamber rim, and being adapted to move to and fromthe bottom of said stationary chamber, said parts being combined,substantially as described.

6. In a pressure device, a closed tank, a Water-supply tank with a pipeleading to said closed tank, a gas-outlet pipe leading from said closedtank, a floating vessel in said closed tank, a perforated tank supportedin said closed tank above said iioating vessel, and valves in said inletand outlet pipes, said parts being combined substantially as described.
